light and power-save mode

RF303

Electrosurgery

Analyzer provides enough

user-selectable test loads

to do routine maintenance

checks on most electrosur-

gery units on the market

today. Compact and por-

table, the device is so

simple to use that techni-

cians can become proficient

with the RF303

within

minutes.

The unit measures ESU

output and high-frequency

leakage, allows for verifi-

cation tests on the return electrode contact quality monitors, and has an

oscilloscope output for waveform viewing. Instantaneous output or select-

able sample times provide extra versatility. The instantaneous mode is

sufficient for most units, but if output readings are variable and require

stabilizing, the signal-averaging mode allows users to manually select two

additional, slower sampling times to produce an accurate average reading.

Modes of operation Line powered, battery powered, offline (battery maintenance
